FOLDABLE BOX AND BLANK THEREFOR.

Specification of Letters Patent.

Patented Feb. 22, 1221.

Application led June 10, 1918. Serial No. 239,094.

To all 'whom z' may concern:

Be it known that I, HARRY L. FnLLowns, a citizen of the United States of America, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Foldable Boxes and Blanks Therefor, of which the following is a specification.

My invention relates to foldable boxes and has for its object improvements in such devices.

In the accompanying drawings- Figure l is the blank from which the box is formed;

Fig. 2 is the same blank on a larger scale, but partly folded, and with attachments secured thereto;

Fig. 3 is the box in finished form; and

Fig. 4 is an enlarged cross-section of the completed box near one end.

Referring to Fig. 1, the part S of the blank between the dotted lines 10 and 11 form the sides S and ends E of the finished box. The parts T of the blank form the top of the finished box. and the parts B form the bottom thereof. The dotted lines l0 and 11 represent lines along which the blank is folded.

In the blank are cut slots l2, 13, 14, 15, 16 and 17. These slots extend from the outer edges to the folding lines 1() and 11. Part of the material between slots 15 and 16, and part of that beyond 17, is dpreferably removed as shown. Corrugate pasteboard is good material from which to form the blank.

Assume the portion of the blank to the left of the cuts 12-17 to be folded over along the line of those cuts and `upon the remainder of the blank. Also, assume the portion to the right of the cuts 14-15 to be similarl folded along the line of those cuts. he extreme ends of the blank will then be brought together at line 18 of Fig. 2. The two ends are then secured together vby a gummed piece of cloth 19.

Another piece of gummed cloth 20 is se` cured alon the outer edge of that part D of the blan which is outside of the line 11 and cut 12. This piece 20 is at this sta e secured onl alon its central portion, tlgie ends being fliee. 'lie free part is that shown extendin to the right of the line 18 and to the left eyond the edge of the blank as shown in F1 2.

' Also, another piece of gummed cloth 2l, of

the same size and shape as 2U, is secured to the corresponding part H of the blank which lies between cuts 13 and 14.

Eyelets 22 are secured in the outer corners of the parts T. Other eyelets 23 are secured in the shortened parts F and (i. 'And still other eyelets 24 are secured in the part which forms the ends lil of the completed box. in these eyeletsat eachV ond is threaded a con! or ta e C. Secured in cach 0nd ll is a laat ton ll' The boay lying Ilat as shown in Fig. 2 is in the condition in whivh it is shipped or lelivered to the trade. Before leaving the` factory, however, the board is broken, that is bent, along the lines 10 and 11, and also along the lines 12-17, 13-16 and 14---1." The box is finished at the place where it is to be used.

To finish or complete the box, the parts are shifted manually 'from flat to rectangular form. This is possible by reason of the patch or gumlned piece 19 connecting the two ends of the blank to form one corner, the other corners being at the bends which are along the lines of the cuts before mentioned. l

As soon as the rectangular shape is thus obtained, the bottom fiaps B are folded inward to form a bottom to the box, and the end fiaps D are folded toward each other over the ends of the bottom flaps B. When this position is reached, the free ends of the gummed patches 2O and 21 are moistened and pasted against the sides S as shown in Figs. 3 and 4.

At this stage of the proceedings there is a com lete box having an open top. To close t e box, the short flaps F and G are bent inward, and the flaps T are similarly bent. The cords C are then ulled tight and wound upon the buttons I. The box is opened by releasing the cords from the buttons and lifting the tops T. As shown ins Figs. 3 and 4, it will be seen that the cords C, when ulled out and wound u on the buttons serve to draw the flaps down so as to close the top of the box and hold said flaps in that position. As shown in Fig. 2, it wlll be seen that, when the cords are released from the buttons and the fla s lifted, the cords assing through the en s E serve to limit t e outward movement of the aps T, F, and Gr. As the boxes are made from corrugated pasteboard, such limitation b the cords serves to prevent injury at the inge connectione along' the line l0 between the sides S and the liaps due to frequent opening and closing of the box, :1nd the bending of the flaps outward when opened.

It is to be observed that in making this box there is practically no waste ol' material. The smell amount ont from the flaps ll` and il boing` l'or uonwnienee nml not by reason oi noveseeity. The bottom flaps B meet each other :it the renter line of the box.y and :tre lielrl in pince by th(- fleps l) and ll which in turn are wvnreil by the gumnieil pieces or patrhm 2U anrl 2l. The top flaps T also meet on th(l renter line oi the box nml are hohl flown by the Corrie (l.

'l`o llsivithe l'lapw ll nnll 'l` inert at the einer line of ihr box. the niillh ol' euch of these flaps nlnet be oqnzil to one-hall'v of the length o'l the ilap ll l'avtn'i-on lie cuts lil and il. Jileo, there is the eamo relati-inship to the Hap l) became l) nel ll are of the saine Size. The relationship lier(` stated is not to the iiape ll anil l) as such` but to the dis lzinrabun'een lne bende in the Central part bfi ivliir'h rome on the lines ol the cute l3-16 unil iii-M15, By making the'cnts l2 to 1T wider, the parte Il and D would be shorter without changing;- the construction. However, these ents are preferably of zi. Width which equals the thicknessA of the material need, and are herein referred to as if they were mere lines without Width. These cuts or lines come at the corners of the completed box.

What Iclsiim is:

1. A box formed of a single piece of bendable material scored on parallel lines to form Aeide, enel, top and bottom Walls, one end of blank the intermediate portion being' transversely ont laterally of the Side ancl end walls und beinhible on eaid parallel lines to provide enil retaining' flops for the bottom welle, and supportingr flaps for the top Walls :unl a tie oord for holding the box in set up 'formation passing through the ends of the top Walls, supporting llaps and end Walls with the outwardly extending end of the cord securerl to the end Wall to holdthe end walls and top well relatively immovable.

2. .l box formed of :i single piece of bendable material scored on parallel lines to form Hille. unil. top unil bottom Walls, one end of :miifl blank and the intermediate portion being' trnneversely ont laterally of the side am! om( wallI anfl benflnble on said parallel linee to provide enrl retaining flaps for the bottoni welle and Supporting flaps for the top walls, the nre-a of the supporting flap being reduced to provide a substantially nn obstructed opening in the top of the box and a. tie cord for holding the box in set up formation passing through the ends of the top walls, supporting flaps and end wells with the outwardly extending end of the cord Securedto the end wall to hold the end Walls and top Well relatively immovable.
